How do i play in 2/2 time?

Question

Ok so what will a whole note, half note, quarter note, eighth note, and sixteenth note become in 2/2 time?

Answer 1

in 2/2 a half note gets one beat, so a whole note gets two beats, a quarter note gets half a beat and an eighth note gets 1/4.  I have never understood why anyone would choose 2/2 over 4/4.  If you have the answer to that, I would like to know.

Answer 2

Actually theres hardly any difference...2/2 is actually 2 minims(2 beats) so 2+2=4 so actually its 4/4 time...only thing u have to take note of is the way u write the pieces in 2/2 time is different in 4/4 time...other than that theres hardly any difference...
